Template parameters problem

[Pierre Chatelier <pierre.chatelier@xxxxxxxxxxxxxxxx>]

Hello,

gcc reports an error that I do not understand; does anyone know if it  
is a bug or some corner case of the standard ?

#include <map>
#include <string>
using namespace std;

void resetBar(const map<int,char>& foo = map<int,char>())
{
}//ok

struct Foo
{
  void resetFoo(const map<int,char>& foo = map<int,char>())
  {
  }//error (main.cpp:11: error: expected ',' or '...' before '>' token
                main.cpp:11: error: wrong number of template  
arguments (1, should be 4))
};

Regards,
